4.1.2 Feedback loops Feedback loops are, “The secondary effects of a direct effect of one variable on another, they cause a change in the magnitude of that effect. A positive feedback enhances the effect; a negative feedback dampens it” (Walker and Salt, 2006, p. 163). Feedback lo...
Negative feedback is not the only type of feedback control that exists. The human body also uses positive feedback loops. In positive feedback, the signal continues to be amplified. The relationship between the signal and the response to the signal is direct, meaning that both the signal and...
There is a feedback when a system's outputs are looped back as inputs, thus becoming a part of a chain of cause-and-effect circuit. There are two types of feedback loops namely, positive feedback and negative feedback. The feedback loops involve a repeating ...

functions, such as signaling processes. positive feedback loops, composed of species and reactions, are necessary for bistability, and generally for multi-stationarity, to occur. these loops are therefore often used to illustrate and pinpoint the parts of a multi-stationary network that are ...
Asymmetric positive feedback loops reliably control biological responses. Mol Syst Biol. 2012;8:577.Ratushny, A. V., Saleem, R. A., Sitko, K., Ramsey, S. A., Aitchison, J. D. Asymmetric positive feedback loops reliably control biological responses. Mol Syst Biol. 2012,8:577....
If feedback loops do in fact exist, then they have to be embodied by particular cell types and inflammatory mediators that communicate among these cells. In addition, specific antigens have to be incorporated as initiators and sustainers of the reaction. Connections, and the forces that ...
Here we investigate why the positive feedback switches that regulate polarization of budding yeast, calcium signaling, Xenopus oocyte maturation, and various other processes use multiple interlinked loops rather than single positive feedback loops. Mathematical simulations revealed that linking fast and ...
